HEAVY-DUTY DIRECT-DRIVE TRANSMISSIONDirect-Drive BLADE features true shaft-to-shaft input power in turning the compressor at 4 pole (1,800 rpm @ 60 hz) motor speeds. The high-efficiency TEFC C-faced motor is direct-coupled to the compressor shaft via a flexible coupling that is engineered for fast and easy element replacement without having to uncouple the drive train.

CAPACITY CONTROLS ADAPT TO YOUR DEMANDSThe demands of every air system are unique, which is why Mattei provides you with three different control schemes (Continuous, Automatic, Modulation) to choose from to best adapt air production to the demands and dynamics of your specific air use.

The Direct-Drive BLADE Series features the state-of-the-art Maestro XB electronic controller to automatically control the compressor.

CONTINUOUS MODEContinuous mode is ideal for applications with heavy air demands where the compressor is under heavy loads. In this case, it is best to run the motor constantly until you decide to turn it off.

AUTOMATIC MODEAutomatic mode is ideal for systems with fluctuating air demands and/or plenty of air storage. It allows the compressor to automatically start and stop the motor to match intermittent air demands.

MODULATION MODEModulation mode automatically adjusts the intake air opening to match output to air demand. It keeps pressure stable within a ± 4-5 psi range. Ideal for applications with little storage and large variations in demand and applications where the compressor runs near full capacity most of the time.

AIR TREATMENTBuilt-in Air cooled aftercooler with 18°F approach temperature. Every Direct-Drive BLADE Series compressor comes with a moisture separator with automatic zero air-loss condensate drain as standard shipped loose for field installation.

MAINTENANCEAll components are easily accessible for fast and easy maintenance. Direct-Drive BLADE Series features quick-change air filters and spin-on oil filters and air/oil separator filters for quick and easy maintenance. Genuine Mattei partsand oil combine with long operating intervals to deliver significant savings over the life of the machine.

DIRECT-DRIVE BLADE SERIES OPTIONAL FEATURES

HEATERS KITThe Heaters Kit option has been engineered to allow you to place the compressor in an ambient as low as +14°F and protect the internal cabinet from freezing.

HEAT RECOVERY KITThe Heat Recovery Kit is a secondary fluid circuit that allows you to pre-heat process water using the heat generated by the air compressor to reduce water pre-heating costs. Maximum outlet water temperature 149-158°F.

During the compression process, air is drawn through a filter into the "Rotor-Stator unit” (RSU) which consists of a cylinder (stator) in which a rotor mounted eccentrically and tangential with the stator rotates. The rotor has longitudinal slots in which vanes slide.

Vanes are pushed against the stator internal surface by centrifugal force, generated by rotation. Air is compressed through the contraction in volume of the chamber, consisting of the stator, vanes and rotor, during rotation. Sealing between the moving parts, cooling and lubrication are ensured by oil injection. At the exit from the RSU, the air-oil mixture passes through a filtering element, separating oil from the air, this oil is then recovered and returns to the intake.

The air-oil mixture leaving the compression unit passes through a separation chamber where velocity slows and gravity returns the bulk oil to the oil reservoir. The air and remaining oil aerosols then pass through a high-efficiency air/oil separator coalescing filter that remove almost all oil residuals from the air. By passing through mechanical and coalescing separation stages, the mixture of compressed air and oil is purified until the maximum oil carry-over in the air does not exceed 3 ppm (parts per million).

A cooling air flow produced by an auxiliary fan passes ambient air through the compressor cabinet and removes heat from the oil cooler generated during the compression. Compressed air leaves the compressor through a valve, which has the function of keeping a minimum pressure inside the oil chamber, so as to ensure suitable operation when the compressor is delivering air.
